Present Continuous vs Present Simple (talking about a summer course)

[angelene001]

The situation is as follows:
I'm on a summer course, somewhere abroad. I'm writing a letter to my friend:
"I'm on a summer course. I'm living in a rented flat. I'm sharing a room with other student"

Is using Present Simple in such a context a mistake?
"I'm on a summer course. I live in a rented flat. I share a room with other student"

It's very stilted.

Can you explain it?

The present continous suggests some form of limited duration, which is appropriate for your sentence.

But what about using Present Simple in such a situation? Is it a grammatical error?

It's not a grammatical error as such. However, as it conveys more of a permanent idea than the present continuous, it is not what most native speakers would use when speaking of their temporary residence during a summer course.
